In the article the physiological foundations and anatomical scheme activity of hypothalamus suprahiazmatic nuclei and connected with them brain’s structures – corpus striatum, hippocampus, epiphysis and dorsal nuclei of suture are work out. On basis of the anatomical scheme and information about features interaction hypothalamus suprahiazmatic nuclei with each of connected with them brain’s structures construct the technically formalized scheme of this physiological system activity. The features of technical formalization of signals, which are generated of the hypothalamus suprahiazmatic nuclei and their feedback loops system – epiphysis, corpus striatum, hippocampus and dorsal nuclei of suture are discussed. Draw a parallel between tuning model coefficients and neurotransmitters, realizing the connection between the brain’s structures, including in the hypothalamus suprahiazmatic nuclei system. The own signal of hypothalamus suprahiazmatic nuclei and output signal system, which created by computer simulation are listed. It is shown, that own signal of hypothalamus suprahiazmatic nuclei contain the components, good for control of different organism’s systems, in particular, muscular system rhythms and second and third heart’s pacemakers rhythms.
